So my Vietnamese fiance is about to submit an application for the Prospective Marriage visa (subclass 300) so we can get married and start a life together in Australia, she has a 3 year old daughter who will also migrate to Australia as well as a dependent child.

We currently have the following (in relation to dependent child)

Divorce Certificate (with certified English translation)

Certified copy of the non-migrating parent’s Identity Card

Certified copy of all pages of the non-migrating parent’s Household Registration Book

There is joint custody with ex-husband but child lives with mother full time.

Form 1229 filled in and signed by the biological father.

Australian Stat Dec stating consent for daughter to migrate/live in Australia and signed by the biological father and cited/signed by a Public Notary.

We are worried that the biological father might change his mind before the PMV is processed, especially if a Case Officer tries to contact him in a few months time and he might regret signing the documents by then.

So my questions are;

Can the biological father suddenly change his mind and invalidate the visa application?

Does a Case Officer even bother to contact the biological father if we have the Form 1229 and a Stat-Dec?

His erratic attitude has us pretty worried and we don't know what he could do to throw our plans into chaos.

Thanks for any advice!

It is not commonly known fact that consent given on Form 1229 can not be withdrawn. It is a one way street, so to say.
Yes, the case officer or an interpreter probably will contact the father.

So if it is locked in with 1229 (and the other docs) what is the purpose of a Case Officer/Interpreter contacting him? - Is there a mechanism by which he could derail my step-daughter from migrating with my fiancé?
